Plastic spraying process and its characteristics
The process principle of plastic spraying Electrostatic powder coating technology through high-voltage electrostatic adsorption to achieve high efficiency coating. The core process is: compressed air will be powder coating conveyed to the electrostatic spray gun, the muzzle of the high-voltage generator produces 80-100kV static field triggered corona discharge, so that the atomized powder charged; charged particles in the electric field under the action of directional adsorption on the surface of the grounded workpiece, along with the thickening of the coating to form a charge buildup, the uniformity of the film through the homogeneous static repulsive autonomy control; and ultimately, the formation of dense film by the high-temperature curing to complete the whole process of industrialized application from powder adsorption to coating formation. The whole process from powder adsorption to coating molding is completed. Workflow Process Name Process Purpose and Detailed Steps Related Equipment Related Materials 1. Pre-treatment Purpose: Remove the pollutants on the surface of the workpiece to form a phosphate layer that prevents rust and enhances adhesion Detailed Steps: ① Degreasing: Acidic de...

In-depth analysis of the entire friction welding process
Friction welding definition Friction welding is the use of relative friction movement of the weldment to produce heat to achieve a reliable connection between the materials of a pressure welding method. The welding process is under the action of pressure, the relative movement of the material to be welded between the friction, so that the interface and its nearby temperature rises and reaches a thermoplastic state, with the role of the top forging force interfacial oxide film broken, the material undergoes plastic deformation and flow, through the interface element diffusion and recrystallization of the metallurgical reaction and the formation of joints. Friction welding principle Two round section of the metal workpiece in the friction welding before, respectively, can be clamped in the rotating chuck and can move forward to pressurize the chuck. At the beginning of welding, the workpiece 1 rotates at high speed, the workpiece 2 moves in the direction of the workpiece 1 and contacts, and a large enough friction pressure is applied to start the friction heating process. After a period of friction, the joint...

The application of automotive aluminum die casting lightweight technology path and practice exploration
Author: Senior Engineer of Ningbo Hexin Molding Co., Ltd (20 years of experience in casting industry) 1. Strategic Value of Aluminum Alloy Materials With the deepening of global carbon emission reduction policy, the automotive industry is experiencing a structural transformation from "steel-based" to "multi-material synergy". Aluminum alloy materials have become the core breakthrough in realizing vehicle lightweighting by virtue of their low-density characteristics and recyclable advantages. In the architecture of new energy models, aluminum alloy die castings have penetrated into the body frame, three electric systems, chassis structure and other key areas, forming a lightweight solution covering the whole body. Current industrial practice shows that the use of modular die casting technology can significantly reduce the number of parts and assembly complexity. Typical cases show that through the structural integration and process innovation, a model of body-in-white successfully realized material weight reduction and production...
